Tool steel for high temperature applications

Most steels can’t stay hard and tough after having been exposed to high temperatures. Fortunately, Toolox® is not like most steels. Even if heated up to 590°C, Toolox® keeps its original hardness when cooled.

Perfect for hot casting and forging

The high-temperature properties of Toolox® make it a perfect steel for casting and forging dies, for tools and machine components in steel mills, cement industries, power plants and in other areas where materials are handled at very high temperatures.

""

Toolox® 44 is used in a hot forging die for chain production. The chain steel is heated to around 890°C before forging, and the die works continuously at 400-500°C.

""

Buckets made in Toolox® 44 can take both wear and heat when handling red hot slag without losing its properties.

""

Brass handles are pressed in a Toolox® 44 die in one stroke at 730-750°C.

Compressive yield strength

""

Y = Rc0.2 (MPa)

X = Soaking time (hrs)

Toolox® 44 compressive yield strength at elevated temperatures and after prolonged soaking times.

Compressive yield strength

""

Y = Rp0.2 (MPa)

X = Testing temperature (°C)

Toolox® 44 has better yield strength at elevated temperatures compared to a H13 standard steel.

Wear resistance

""

Y = Hardness (HBW)

X = Temperature (°C)

Both Toolox® 33 and Toolox® 44 have better hot wear resistance than Q&T 450 HBW and 500 HBW abrasion-resistant steels at elevated temperatures.

Impact toughness

""

Y = Charpy-V impact toughness (J)

X = Testing temperature (°C)

Toolox® 44 has much better toughness compared to conventional hot work tool steels at both room temperature and at elevated temperatures.
